ELECTRIC DRYING AND IRONING APPARATUS- Specification of Letters Patent.

Patented Jan. 30, 1906.

Application filed March 28, 1905. Serial No. 252,592.

TO/(ZZZ whom it may concern:

Be it known that I, GEORGE W. RICHARD- SON, a citizen of the UnitedStates, residing at Wissahickon, in the county of Philadelphia, State ofPennsylvania, have invented certain Improvements in Electric Drying andIroning Apparatus, of which the following is a specification.

This invention relates to apparatus designed particularly forelectrically drying and ironing blue-print paper; but it is also adaptedfor drying and ironing various other ma terials. It avoids the presentuse of wringers and drying-boxes and effects a material saving in timeand labor.

The nature and characteristic features of the invention will fullyappear by reference to the following description and the accompanyingdrawings in illustration thereof, of which Figure 1 represents a topplan view, par tially in section, of an apparatus embodying myimprovements. Fig. 2 represents the same in rear elevation and partialsection. Fig. 3 represents an end elevation thereof. Fig. 4 represents atransverse vertical sectional view thereof, and Fig. 5 represents asectional elevation of a roller and its.connections.

As shown in the drawings, the base 1, adapted to be connected to anysuitable support, carries the casing 2, preferably made of rass. Thecasing ends 2 have journaled therein the rollers 3, and the material ofthe body is formed in the curves 2 conforming to the rollers andproviding an inlet i and an outlet 5, connected by a passage 6 forpassing the paper between the rollers. The inlet is provided with aguide-plate 7 and with the roller 8, mounted in the struts 9, supportedby the casing, for feeding the material.

The channel 6 is formed by the plates 10, supported by the plates 1 1and 12, connected with the casing, the lower part of the plates 11 beingbent to conform to the contour of the rollers. The space within theplates 10, 11, and 12 is packed with heat-insulating material 1 3, andthe spaces occupied by the rollers 3 are lined with heat-insulatingmaterial 14.

The rollers consist of the hollow brass cylinders 3*, supported by hubs3 journaled in roller-bearings 2, carried by the ends of the casing.Within each cylinder 3 is a cylinder 3-, of insulating material,supported by the hubs 3 and wound with fine wire 3 The wire is connectedwith a ring 3 attached to the part 3 projecting from the hub, by theinsulating-ring 3 the ring and the wire throughout the length of thecoil being insulated and the coil being grounded at its termination inany suitable way, as by the connection 3 Brushes 15 bear upon theseveral rings 3 and are supported upon the insulating-bearings 16, theseveral brushes being connected by the binding-posts 17 with conductors18.

The several rollers have pinions 19 fixed to the ends thereof, thevertical pairs of rollers having their pinions in en agement.

A pinion 20, driven by the s aft 21, meshes with a corresponding pinionof each vertical pair, so that the rollers may be operated by the shaft21 to feed the paper therethrough.

It will be understood that in the operation of this mechanism the paperhas the water and moisture squeezed and dried therefrom by passing itthrough the rollers 3, revolved together by the shaft 21 and heated bycurrents passing through their respective coils.

Having described my invention, I claim 1. In apparatus of the classdescribed, drying and ironing mechanism comprising a plurality ofrollers coacting to press and dry material passed therethrough, each ofsaid rollers comprising a brass ironing-cylinder, a resistance-coiltherein adjacent thereto, bearings for said rollers, a conductorconnected to and revolving with each of said rollers, means forinsulating each of said. conductors from the respective cylinders andbearings, and a brush making contact with each of said conductors incombination with a casing having end walls disposed between saidironing-cylinders and brushes, substantially as specified.

'2. In apparatus of the class described, a casing having a passagetherethrough, and a plurality of rollers journaled in said casing andcoacting to press material in said passage, the respective rollerscomprising a brass ironing-cylinder and a resistance-coil located in andconcentric to said cylinder, substantially as specified.

3. In apparatus of the class described, a casing having closed ends,ironing rollers j ournaled in said ends, the body of said casingconforming to said rollers and forming passages thereto, and therefrom,and a resistance-coil in each of said rollers, substantially asspecified.

4:. In apparatus of the class described, a casing. having closed ends,ironing rollers journaled in said ends, and a guideway in said casingbetween pairs of said rollers, said casing having an inlet to and anoutlet from said rollers and guideway, substantially as specified.

5. In apparatus of the class described, a casing having closed ends,ironing-rollers journaled in said ends, plates supported by said casingand forming a guideway between pairs of said rollers, and feedingmechanism
